I don't know where to plug this question in; it may be similar to the question on tokens which never got a clear answer that I could find.

I need to have the XML module communicate with the page it is embedded in. I will be querying an XML service that can send back one of up to 6000 possible categories of text/data. I don't want to build 6000 pages with each XML query hand-embedded.

Is there any way to get the QueryString of the host html page to pass to the XML module and be appended to the XML source URL.?

If there isn't, is there somewhere to add this function to a wish list for the XML module?

I am looking into writing my own modification of the core XML module to do this; I would like to get the function into the core module so that I wouldn't need to update my version every time there is a new DNN version.

I have modified the XML module to do exactly what you are trying, you are welcome to it although I have NOT put it into an installable module.  This is why I have not released it on the community.  We are using it extensivly in an important work related project.  If you interested then please email me at simon at chi.swan.ac.uk (obviously need to change - do not want spam bots seeing this email address), if you get no answer in 24 hours try again as my anti spam is an agressive little beast.

I am trying to get the DNN team to start devloping the XML module again, so that this funcationality can be added to the core product.
